I feel your pain, going through the exact same thing right now. Here is what i decided to do:

Go the Dave Barton's site, buy one yellow FEMALE sealed bullet terminal WIRE INSERT and by one black FEMALE sealed bullet terminal WIRE INSERT, i think they are 4 bucks each.

These fit right on the Bosch pump. I'm almost positive the wires to the main pump are yellow and black and of course match the yellow and black plastic on the pump.

Hope that helps
